  • a portable lifting mechanism is also known from US 4,434,973.
  • This hoist uses a high gear ratio to apply the load even without a brake keep the motor stationary.
  • the disadvantage of this solution is: this hoist is not universally applicable and is not easy to transpose, among other things, because it has no balanced focus.
  • the housing also protects it Hoist not complete. In addition, it is complicated and expensive, making it is also not suitable for the home area for these reasons.
  • the object of the invention is to provide an inexpensive, universally applicable To create wind power especially for home use by one person is relatively easy to transport without any additional aids.
  • the solution provides that the box-like, in size and shape like a suitcase trained housing on an outside a suspension and on the Opposite outside an opening for the passage of the traction device and can be transported by one person in the manner of a portable windmill and that the electric motor, the gearbox and the traction roller in one common preferably horizontal plane.
  • the usability of the winch can be improved if the suspension of the flat housing centrally on one of the two flat sides and the opening centrally are arranged on the opposite flat side.
  • the housing is expediently made of two detachably connected to one another Housing halves formed.
  • the housing has a long side Handle on.
  • control unit should have one in the housing arranged receiver unit can be operated remotely.
  • Network-independent operation can be achieved if a power supply is switched off at least one accumulator accommodated in the housing is provided.
  • the accumulator can expediently be charged via the power cable.
  • a winding element arranged on the housing can be manually wound up.
  • the winding of the power cable can be easily done when on the same Several winding elements for the power cable are provided on the transverse side.
  • a suitcase-like, i.e. flat winch can be obtained inexpensively with little technical effort if the electric motor as a universal motor and the gear as self-locking worm gear trained and if the Universal motor is connected to the worm gear via a belt drive.
  • the belt drive used here together with the worm gear is predestined for a flat design.
  • a belt drive is usually out Safety reasons not used for hoists; here is the use of the universally applicable winch as a hoist but still ensured.
  • FIG. 1 shows the wind power plant in a schematic three-dimensional representation a housing 1, which consists of two housing halves 1a, 1b.
  • the box-like flat housing 1 resembles a suitcase in size and shape.
  • the upper flat side (outer side 3a) is a suspension 2 in the form a fold-out hook 2a arranged.
  • an opening 3c (see FIG. 5) through which an Traction means 4 is in the form of a rope 4a, with at the end of the traction means 4th attached load suspension device 5 (hook 5a).
  • the two detachable housing halves 1a, 1b are firmly connected to one another in the operating state.
  • FIG. 2 shows the windmill according to FIG. 1 without the two housing halves 1a, 1b.
  • the Windwork consists of one that can be operated with direct and / or alternating current Electric motor 6 with a downstream gear 7 and a traction roller 8 for opening and unwinding the traction means 4.
  • the motor shaft of the electric motor 6 is with the Gearbox input shaft of the gearbox 7 rotatably connected, on the Gearbox output shaft in turn the traction roller 8 is seated.
  • the traction device 4 is over another roll 9 led down.
  • 2 also shows the housing 1 arranged power supply 10, in the embodiment in the form of Accumulators 10a. (Of course, the term energy supply 10 here connection to a power supply included.)
  • a charger 11 is also housed in the housing
  • a control unit 12 in the housing 1 present, which has an infrared receiver unit 13 (see FIG. 7), the input is accessible from the outside.
  • the control unit 12 serves to control the movement of the Electric motor 6.
  • the traction device roller 8 is a rope drum when using a rope as a traction device 4 (and a sprocket when using a chain).
  • the electric motor 6, the energy supply 10 and the transmission 7 are located and the traction roller 8 in a common plane.
  • the suspension 2 of the flat housing 1 are centrally on one of the two flat sides (outer sides 3a) and the opening 3c centrally on the opposite flat side (outside 3b) arranged. This results in the operation of the suspended wind turbine in essentially a horizontal position.
  • Fig. 3 corresponds to Fig. 2, but without the batteries 10a and the charger 11 and the control unit 12.
  • 4a and 4b show a schematic illustration of the wind power plant with a or with two hooks 2a as suspension 2.
  • Fig. 6 the windmill can be seen as a "suitcase" ready for transport, with the upper longitudinal side of the housing 1, a handle 14 is present.
  • the windwork is like a portable device due to its shape and weight a person can be carried relatively comfortably.
  • winding elements 15 are on the left front of the Housing 1 winding elements 15 are arranged, on which a power cable 16th can be wound up.
  • the power cable 16 is through a housing opening 17th passed and connected to the controller 12 and the charger 11.
  • the windmill itself can also be supplied with electrical energy via the power cable 12 be supplied.
  • FIG. 7 shows the housing 1 of the windmill according to FIG. 6 from the other side seen so that the infrared receiver unit 13 can be seen.
  • An interior compartment (not shown) is also provided in the interior of the housing 1, that is accessible from the outside and in which e.g. the hook together with the rope can be accommodated. It is advisable to set up an accessory compartment because the interior always has usable free space.
  • Fig. 8 shows a preferred constructive solution for a flat windmill with a cuboid housing 101 in a schematic representation from above seen that can be used in particular as a small hoist.
  • the housing 101 are an electric motor that can be operated with direct and alternating current 102, a brake 103 with the schematically represented elements 103a and as Gear a worm gear 104 and as a traction drive (traction roller or Traction mechanism drum 105) a cable drive arranged in a common plane. (Alternatively, a chain drive and the like can also be provided as the traction mechanism drive.)
  • it is also common to move the brake into the electric motor or the To operate the electric motor so that it functions as a brake in a specific operating mode is effective.
  • FIG. 8 shows, the motor shaft 108 runs parallel to the axis of rotation 109 of the Worm gear 104.
  • the motor shaft 108 is connected to the axis of rotation 109 via a Belt drive 110 connected, the belt 110a via a as a pulley formed drive wheel 111 is guided, the output side on the motor shaft 108 sitting.
  • a wheel 112 driven by the belt 110a is on the axis of rotation 109 of the Worm gear 104 attached.
  • the one from the worm gear 104 directly driven traction roller 105 is located within a support frame 106 spatially between the universal motor 102 and the worm gear 104.
  • FIG. 8 shows that the axis of rotation of the traction roller 105 perpendicular to the axis of rotation of the Worm gear 104 runs.
  • the traction means 113 is by a not shown Housing opening led outwards.
  • the universal motor 102 has motor windings connected in series and will therefore also referred to as a commutator series motor. It is only a motor operable (so-called 2-quadrant operation), so it does not generate a generator Moment and therefore cannot be braked by the generator moment.
  • the two motor windings of the universal motor 102 consist of one Rotor winding and one or more stator windings.
  • the two stator windings arranged parallel to each other on both sides of the rotor winding intended. All three motor windings are connected in series during motor operation.
  • the worm gear 104 is designed to be self-locking.
  • the self-locking is set so that even the greatest load with the universal motor 102 stopped Worm gear 104 is held.
  • the self-locking worm gear 104 acts when lifting and Lowering therefore like a constantly effective brake.
